We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).

New submitter FuzzNugget writes "A recent catastrophic hard drive failure has caused me to ponder whether the trade-off between security and convenience with software-based OTFE is worthwhile. My setup involves an encrypted Windows installation with TrueCrypt's pre-boot authentication, in addition to having data stored in a number of TrueCrypt file containers. While it is nice to have some amount of confidence that my data is safe from prying eyes in the case of loss or theft of my laptop, this setup poses a number of significant inconveniences." Read on below; FuzzNugget lists some problems with this set-up, and seeks advice on a simpler system for backing up while keeping things locked down.

An anonymous reader writes "You see those stories popping up every now and then — new Dreamcast game released, first SNES game in 15 years etc — but an in-depth feature published today takes a look at the teams behind the retro revival, and looks at why they do what they do. Surprisingly, there seems to be a viable audience for new releases — one developer says his games sell better on Dreamcast than they do on Nintendo Wii. Even if the buyers vanished, the retro games would still keep coming though: 'I wager I'd have to be dead, or suffering from a severe case of amnesia, to ever give this up completely,' says one developer."Update: 03/23 18:28 GMT by T: If you want to play original classic games on new hardware, instead of the other way around, check out Hyperkin's RetroN 3, which can play cartridges from 5 classic consoles.

Nerval's Lobster writes "IBM announced this week that it has developed a way to manufacture both logic and memory that relies on a small drop of 'ionic liquid' to flip oxides back and forth between an insulating and conductive state without the need to constantly draw power. In theory, that means both memory and logic built using those techniques could dramatically save power. IBM described the advance in the journal Science, and also published a summary of its results to its Website. The central idea is to eliminate as much power as possible as it moves through a semiconductor. IBM's solution is to use a bit of 'ionic liquid' to flip the state. IBM researchers applied a positively charged ionic liquid electrolyte to an insulating oxide material — vanadium dioxide — and successfully converted the material to a metallic state. The material held its metallic state until a negatively charged ionic liquid electrolyte was applied in order to convert it back to its original, insulating state. A loose analogy would be to compare IBM's technology to the sort of electronic ink used in the black-and-white versions of the Kindle and other e-readers. There, an electrical charge can be applied to the tiny microcapsules that contain the 'ink,' hiding or displaying them to render a page of text. Like IBM's solution, the e-ink doesn't require a constant charge; power only needs to be applied to re-render or 'flip' the page. In any event, IBM's technique could conceivably be applied to both mobile devices as well as power-hungry data centers."

Probably -- if the device I want supports itProbably -- if it works as promisedProbably -- credit cards will be like checks in another decadeNot sure -- no strong opinions either wayDoubtful -- not a useful technology to meDoubtful -- it will be too fragmentedDoubtful -- privacy/security concernsDoes throwing my spare change at the cashier count as mobile?
